Publishable summary: The main objective of the CORALIS project is to create pathways for the decarbonization of resource and energy intensive sector value chains through the implementation of viable industrial symbiosis approaches combining new business and management strategies with innovative technology-based enablers. This whole approach will be demonstrated in three real industrial areas covering different sectors, geographical dimensions, and resources, improving the knowledge basis and laying the foundations for exploiting the potential of Industrial Symbiosis in EU process industry.
The main goal of the deliverable is to analyze the three CORALIS demonstration sites from an energy- and resource efficiency perspective, and to facilitate the further opportunity identification process at the demonstration sites and beyond. These demonstration sites are:
• Escombreras (Spain): A novel process for KNO3 production enabling the use of by-products (HCl, H2SO4 and CO2), residues (Ca contained in wastewater) and emissions (CO2 reduction) of the industrial area.
• Wa3rm (Sweden) An integrated unit for CO2 capture and waste heat recovery from a steel plant and/or pulp mill company will be installed to supply a greenhouse.
• Brescia (Italy): A collaborative scheme for industrial waste exchange and valorisation will be implemented in a total of four industries. The objective is to use metal powder, oxides and other industrial wastes for producing steel, pig iron and aluminium, as well as to substitute coal by biogenic materials.
The work was conducted in two parts. Part one focused on conducting two literature reviews; one on knowledge developed in previous SPIRE projects and practice, and one focusing on current trends in society and research. Part two focused on understanding and discussing the work done at the demonstration sites within the CORALIS project and how they had identified the IS opportunities, identifying strengths and improvement potentials in the currently used processes.
The results and conclusions of the deliverable are in part general, e.g., that opportunity identification is a process that is complex and “human-centered”, and that there might be a need to rethink the tools and methods used for opportunity identification in industrial symbiosis. They are also specific in the context of CORALIS, including suggestions for how to identify potential revalorization opportunities in the demo-sites, both during the project and beyond.
